COSEWIC assessment and status report on the white wood aster, Eurybia divaricata, in Canada.: CW69-14/51-2024E-PDF
"This herbaceous perennial plant is found in the temperate forests of eastern North America, reaching the northern limit of its range in Canada. Thirty geographically-restricted and isolated subpopulations occur in patches of deciduous forest in extreme southern Ontario and southwestern Quebec. Recent surveys have found additional subpopulations, with over 100,000 known mature plants in Canada. The change in status reflects this higher estimate of abundance, and changes to the way that criteria are applied. However, the species is still threatened by habitat loss and degradation due to housing, recreational activities, agriculture, and forestry, as well as invasive species and deer browsing"--Reason for designation, page iii.
